What kind of bag should I use for my carry-on on the airplane? Is a tote bag okay?

Im going on a plane and I dont know if a tote bag is okay to use. Also, can I take extra batteries for my digital camera? What about my iPod?

A lot will depend on your airline. On most airlines, you are allowed one carry on bag and one personal item (such as a laptop, camera bag, purse, etc.) When choosing a carry on bag, it is best to first consult your airline's carry on baggage allowance. A good bag will fit either under the seat in front of you or in the overhead luggage bins. It is a good idea to use a bag without a hard outside shell so that if it is a tight fit, you can hopefully squeeze it in. If your carry on bag is too big- don't worry- it's not the end of the world. U.S. domestic carriers allow you to "gate check" your bag. In this event, you would leave your bag at the end of the boarding bridge and retrieve it on your way out of the plane at your arrival city.
